Mass And Volume Relationship

Mass and Volume Relationship Purpose: The purpose of the research lab was to disclose out if there is a constant birth surrounded by mass and volume of a precondition substance which happens to be wet. Volume of body of wet (mL)Total mass of water and piston chamber (g) 0.00100.425 10.00110.354 20.00120.269 30.00130.231 40.00140.234 50.00150.247 60.00160.181 70.00170.119 80.00180.043 90.00189.974 100.00199.963 Data and observations: Calculations: Subtracted the mass of the 10mL of H2O: 100.354-100.425=9.929 20mL: 19.844g 30mL: 29.806g 40mL: 39.809g 50mL: 49.822g 60mL: 59.756g 70mL: 69.694g 80mL: 79.618g 90mL: 89.549g 100mL: 99.583g Questions: 1: The volume predicted for 36g of water is? 2: The mass predicted for 54cm3 of water is? 3: The percent defect was found to be? Slope from #2-0.998g/mL x 100 4. a. What happens to the assiduousness of water if the volume is cut back by one fractional? D=M/V- 99.538g/ 100mL= 0.99 538 49.822/50mL=0.99644 b. Do you think that density stick out be apply to identify a substance? Yes because a substances density is specialised and it can be used to ascertain one spurn from another but not on a very(prenominal) accurate scale. Conclusion: 1.Results of main object: 2: secondhand objectives and or trends: Pipet used to conduct small amounts of water Balance is used to measure the mass Graduated piston chamber is used to measure the volume of the water The surface looked the likes of it had retell dipped when it was in the receive cylinder. 2.Possible experimental errors: a)putt a little too much water into the graduated cylinder. b)Not wait on the whole until the number stopped. c)Not checking to turn back if the number was completely on zero. d)Not checking if the surface on the balance was clean and not wet. e)Calculating numbers wrong.If you necessity to get a full essay, raise it on our website: OrderCustomPaper.com
